YAML Question: Using YAML::YamlNode#transform Method to get float values?

[RubyQuestions]

I'm trying to use the transform method in YAML to grab the values from
my
classes. Everything works correctly, except when I try to get the
price data (Floats) from my class. I'm trying to understand if I
should be doing something different.

Thanks.

Here is my sample script and IRB session:

require 'yaml'

class Video
attr_accessor rice, :title, :director, :year

def initialize(p, t, d, y)
@price = p
@title = t
@director = d
@year = y
end
end

myVideoCollection = [
Video.new(22.45, "Moonshine Hustler", "Moose McDaniel", 1928),
Video.new(19.72, "Crazy Cool Camels", "Rob Crowfeet", 1985)
]

videos = {"Videos" => myVideoCollection}

##########IRB#############
irb(main):035:0> puts videos.to_yaml
---
Videos:
- !ruby/object:Video
director: Moose McDaniel
price: 22.45
title: Moonshine Hustler
year: 1928
- !ruby/object:Video
director: Rob Crowfeet
price: 19.72
title: Crazy Cool Camels
year: 1985
##########################

videoListYaml = YAML:arse(videos.to_yaml)

Summary
#########################
irb(main):065:0> p videoListYaml.select("Videos//title").transform
["Moonshine Hustler", "Crazy Cool Camels"]

## WORKS...

irb(main):066:0> p videoListYaml.select("Videos//director").transform
["Moose McDaniel", "Rob Crowfeet"]

## WORKS...

irb(main):067:0> p videoListYaml.select("Videos//year").transform
[1928, 1985]

## WORKS...

irb(main):068:0> p videoListYaml.select("Videos//price").transform
[#<YAML::Syck:omainType:0x2be0888 @value="22.45",
@type_id="float#fix", @domai
n="yaml.org,2002">, #<YAML::Syck:omainType:0x2be04e0 @value="19.72",
@type_id=
"float#fix", @domain="yaml.org,2002">]

## Why isn't this parsing out the two Float values for price?
